RING 0R BAND FOR USE IN FILE-DRIVING.

Application filed August 12, 1916. Serial No. 114,508.

To all whom it may concern:

Be it known that I, HENRY ILLBAoK, a citizen of the United States,residing at East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Rings or Bands forUse in Pile-Driving; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and tocharacters of reference marked thereon, which form a part of thisspecification.

The present invention relates, generally, to improvements in rings orbands, such as are used with piles during the operation of driving. thepiles in position; and, this invention has reference, more particularly,to a novel construction ofmetal ringor band, for use with piles whiledriving the same in place, with a view of providing a ring or band whichwill not break while subjected to the constant blows of the drop orhammer of a pile-driving machine.

It has been found in practice, that with the solid rings or hands nowused with piles, during the driving operation, the constant blows fromthe heavy drop or hammer employed, often breaks or cracks the ring orband, and, furthermore, on account of the great heat produced, theexpansion of the metal or of the upperend-portion of the pile, veryoften results in the splitting or breaking of the rings. A

The principal object of the present invention, therefore, istojprovide anovel and simply constructed ring or band, adapted to be placed uponthe. upper end of a pile, which is subject to expansion, and which willnot split or break when subjected to the blows from the heavy droporhammer of the pile-driving machine, during the operation of drivingthe pile-in place.

Other objects of this invention not at' this time more particularlyenumerated will be clearly understood from the following detaileddescription of the present invention.

With the various objects of the present invention in view, the saidinvention consists,

. essentially, in the novel ring or band for use with piles; and, theinvention consists, furthermore in the general arrangements andcombinations of the various parts thereof, as well as in the details ofthe construction of Specification of Letters Patent.

scribed in the following specification, and

then finally embodied in the clauses of the claim which are appended toand which form an essential part of the said specification.

The invention is fully illustrated in the accompanying drawings, inwhich Figure l is a top-edge view of a ring or band, certain partsthereof being represented in horizontal section, said view illustratingone embodiment of the principles of the present invention.

Fig. 2 is a side view of the said ring or band; and Fig. 3is a similarview of the opposite side of the ring or'band.

Similar characters of reference are employed in the said above describedviews to indicate corresponding parts. p I

Referring now to the said drawings, the reference-character 1 indicatesa complete ring or band for the purposes herein-above stated, and madeaccording to and embodying the principles of the present invention.

From an inspection of Fig. 1 of the drawings, it will be seen that thering or band 1, which may be of any suitable size, both as to itsdiameter and its width, consists of a plurality of ring-shaped elements,usually two of such elements as 2 and 3 being employed, said elements 2and 3 being spirally disposed, and having the overlapping end portions4, 5, 6 and 7, arranged substantially as shown in said Fig. 1 -of thedrawings. The said overlapping end-portions are suitably rigidly securedtogether by means of rivets 8 and 9, or by means of other suitablefastening devices. At a pointopposite thesaid overlapping end-portions,the said ring-shaped elements 2 and 3 have contacting portions as 10 and11, said contacting portions being also rigidly secured together bymeans of a rivet 12, or by means of other suitable fastening means, aswill b'e clearly evident.

The said ring-shaped elements 2 and '3 are of such construction, that,when arranged and secured in their assembled relation, the

driving the pile in place, by placing the ring or band upon the upperend of the pile, and then subjecting both the ring or band and the endof the pile to a succession of blows from a heavy drop or hammer of apiledriving machine.

Heretofore, in practice, solid rings or bands have been employed forthis purpose, and it has been found that due to the heat created, theexpansion of the metal-ring or band would very often crack or split, orsuch breaking of the ring or band would sometimes be caused by the forcedue to the compression of the end of the pile.

With the form of ring or band made according to the principles of thepresent invention, the spaces 13 and 14 between the two ring-shapedelements 2 and 3, readily permit of sufficient expansion of the innerring-shaped element 3, without any danger of shearing or cutting therivets 8, 9, or 12, and at the same time overcoming the possibility ofthe complete ring or band splitting, cracking, or breaking, asheretofore with the employment of the usual solid ring or band.

I claim 1. A ring or band for use in the driving of piles, comprising aplurality of ring-like members, one set of end-portions of a pair ofsaid ring-like members being arranged end to end and disposed betweenthe other endportions of said ring-like members, and means for securingsaid ring-like members in assembled relation.

2. A ring or band for use in the driving of piles, comprising aplurality of spirally disposed ring-like members, one set ofenclportions of a pair of said ring-like members being arranged end toend and disposed between the other end-portions of said ringlikemembers.

3. A ring or band for use in the driving of piles, comprising aplurality of spirally dis posed ring-like members one set ofend-portions of a pair of said ring-like members being arranged end toend and disposed between the other end-portions of said ringlikemembers, and means for securing said ring-like members in assembledrelation.

4:. A ring or band for use in the driving of piles, comprising aplurality of ring-like members arranged one within the other, means forsecuring said ring-like members in assembled relation at diametricallyoppo site portions, said ring or band being formed with open spacesintermediate of the secured portions of said ring-like members.

5. A ring or band for use in the driving of piles, comprising aplurality of spirally disposed ring-like members, arranged one Withinthe other and having overlapping end-portions, means for rigidlysecuring said over-lapping end-portions, said spirally disposedring-like members being spaced apart so as to provide an open portionfor ex pansion.

6. A ring or band for use in the driving of piles, comprising aplurality of spirally disposed ring-like members, arranged one withinthe other and having over-lapping end-portions, means for rigidlysecuring said over-lapping end-portions, means for rigidly securing saidring-like members at a point diametrically opposite their over lappingend-portions, said ring-like members being spaced apart intermediate ofsaid secured portions so as to provide open spaces 7 for expansion.

7 A ring or band for use in the driving of piles, comprising a pluralityof ring-like members arranged one within the other, rivetsfor securingsaid ring-like members in assembled relation at diametrically oppositeportions, said ring or band being formed with open spaces intermediateof the secured portions of said ring-like members.

8. A ring or band for use in the driving of piles, comprising aplurality of spirally disposed ring-like members, arranged one withinthe other and having over-lapping end-portions, rivets for rigidlysecuring said overlapping end-portions, said spirally disposed ring-likemembers being spaced apart so as to provide an open portion forexpansion.

9. A ring or band for use in the driving of piles, comprising aplurality of spirally disposed ring-like members, arranged one withinthe other and having overlapping end-portions, rivets for rigidlysecuring said overlapping end-portions, a rivet for securing saidring-like members at a point diametrically opposite the said rivetedoverlapping end-portions, said ring-like members being spaced apartintermediate of said secured portions so as to provide open spaces forexpansion.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 9th day of August, 1916.

HENRY ILLBACK.
